Users are provided with the option to schedule the sending times of their emails. On the Review & send page, click the Schedule for later link. In the scheduling window that appears, set the date and time of send-off. If you’d like to receive a “heads up” email notifying you that the email is about to send, type in your email address (separate multiple addresses by commas) in the field below.
If you need to edit a scheduled email, head back to the Campaigns page and click on the Scheduled tab, (this tab only appears if you have scheduled emails).
Select Cancel this mailing from the options menu to the right of the email name. Then, make your edits to the email, click Review and send, and schedule the send again by clicking Schedule for later at the bottom of the page.
